Which way would you fall if you were in the center of the earth?

The force of gravity is zero at the earth's centre. So there would be no specific direction to fall.
One interesting fact is that if evacuated tubes were drilled between any two cities on Earth, the travel time between any pair of cities would be 42 minutes! 21 min accelerating and 21 min decelerating. This time is constant whether the tubes went through the centre of the Earth or not. (Thanks Lewis Carroll.)

Why a falling object subjected to earth's gravity does not continue to accelerate forever?
It does ! The amount is insignificant. Look at it another way, the moon is always falling toward the Earth ... and the Earth is always falling toward the moon. They are both accelerating.
How do scientists know how hot the core is?
The heat present in the Earth is due to several factors. The first source of heat is from the remnants of heat from impacts with planetesimals early in Earth's history. Impacts with large bodies such as these (including the impact which led to the formation of the moon) trapped the thermal energy of the collision in the surrounding rock of the planet, and may have been enough in certain circumstances to completely melt the early Earth. The second source of heat is also a remnant of an early Earth event known as the Iron Catastrophe. With much of early Earth still molten, denser metals, particularly iron and nickel, migrated to the center of the planet. Tremendous amounts of frictional heat was created, enough to completely melt the planet once again. The third source of heat in the Earth is from compression due to gravity. The fourth and final source of heat in the Earth is from the decay of radioactive elements. This source of heat is gradually declining due the decreasing amounts of radioactive isotopes, the decrease being caused by the decay.
Do wrist watch show correct time during free fall?
Yes the free falling wrist watch would function in the same way as it was in the rest condition.
Where is the center of universe located and how far is it from solar system?
It seems that the Universe has no center. It is generally believed that the Universe looks roughly the same way wherever you are; wherever you are, it looks as if you are at the center.
What will happen if roots grew randomly in the soil instead of responding to gravity?
Yes because if the roots grew randomly then the plant would fall over or grow in a strange way (sideways) because the gravity is not helping support the tree to stand. Another reason is because the gravity is pulling the roots down, therefore the roots will be stronger and let the tree stand up straightly in direction to the centre of the earth.
How many mph would you be going when you came out the other side if you fell in a whole that went all the way through the earth?
You wouldn't. Aside from the fact that you would burn up as you reached the earths core, you have to think of gravity.If you have a hole on one side of the earth and you fall in it you would fall to the center of the earth. If there was a hole on the exact opposite side of the earth and the fellow over there fell into it he would fall toward the center of the earth. If both holes went to the center of the earth and were joined, and molten magma didn't come out, then I would reason that you would fall no further than the center.
Why do people not fall to the center of the Earth?
Because the ground is in the way!
Why earth is not falling down?
Well, for one thing, at every place you've ever been in your life, or are ever likely to be, "down" is always the direction toward the center of the Earth. When you think of it that way, it would be pretty weird to expect the Earth to fall toward the center of the Earth, wouldn't you say ?
Can you get to the center of the earth?
No, you can not get to the center of the earth. The core of the earth, which is the center of the earth, is way to hot. It would be like standing on the sun, but though the core of the earth is EXTREMELY hot, it can not compare to the heat of the sun
What happens in the center of the Earth?
There is a blazing heat in the molten metal. If you fall down a volcano it is a one way path to the core of the earth and it is impossible to get out again.
What challenges stand in the way of sending explorers to the center of the earth?
The center of the Earth is way too hot for any human being to survive. there are no materials that would withstand the heat either so nothing can transport humans into the center of the Earth.
How deep would you drill to reach the center of the earth?
If you to dig one foot per minute, then it would take six years to get the center of the earth. INCORRECT. The Earth's diameter is approx 8,000 miles, making the radius (distance to the center of the sphere) approx 4000 miles. A mile is 5,280 ft, and 4,000 of those = 21,120,000 ft. If you could dig one foot per minute, as stated by the previous answer above, then there are 525,600 minutes in a year. Now, divide the amount of total feet (21,120,000) by the number of feet per year (525,600) to get how long it would take to dig to the center of the earth, which is a little over 40 years. that's how long it would take. 40 YEARS. If someone fell into a hole and was in a free fall all the way down, it would take over 30 hours to free fall to the center of the earth. "If someone fell into a hole and was in a free fall all the way down, it would take over 30 hours to free fall to the center of the earth." INCORRECT. I'm pretty sure you forgot to calculate the increase in gravity as you travel closer to the core
Will Earth ever fall into the black hole at the center of the Milky Way Galaxy?
It's a possibility but not withing billions and billions of years.
Why does the sun orbit the center of the galaxy?
Gravity! If the Sun (and all other stars and objects in the Milky Way) didn't orbit the center, they would eventually fall in to the central super-massive black hole at the center of the Milky Way.
Why don't satellites crash if gravity is attracting them towards the center of the earth?
Because they are in orbit which means they have enough forward motion to keep them into a state of "Free Fall". A satellite is falling to earth's center due to gravity. But for every inch it falls toward earth, earth move out of it's way by one inch.
If you dig a whole down can you penetrate into outer space?
Nope. If you could dig all the way through the earth, you would have a hard time with the center. It's molten rock. Hot and nasty. Gravity pulls everything in to the center. It makes sense that if you could make it to the center then the dirt from the other side would fall in. But no you couldn't do it. Cool thought though!!
Is earth moving to the center of the milky way?
no.
